What Is Alzheimer's Disease?
Alzheimer鈥檚 Disease vs. Dementia
Alzheimer鈥檚 disease is the most common cause of dementia鈥攁 general term for loss of memory, language, and other thinking abilities). Alzheimer鈥檚 disease accounts for 60 to 80 percent of dementia cases. Unlike occasional forgetfulness, dementia caused by Alzheimer鈥檚 disease is severe enough to interfere with you or your loved one鈥檚 everyday life.
Alzheimer鈥檚 is a progressive disease that has no cure. The large majority of Alzheimer鈥檚 disease diagnoses occur in people ages 65 and up. However, it may occur earlier in rare cases.

- Loss of bladder or bowel control
- Weight loss
- Seizures
- Difficulty swallowing
- Difficulty completing common tasks that were once familiar, such as driving, performing job duties, doing finances, and managing medications
Alzheimer's Disease Stages
As symptoms and stages may overlap, it鈥檚 difficult to place an individual into one stage:
- Mild dementia鈥As Alzheimer's disease progresses, memory and cognitive problems may begin to effect daily life and performing activities.
- Mild cognitive impairment鈥You or your loved one may begin to struggle with memory, thinking, judgment, or language.
- Moderate dementia鈥Memory loss, confusion, and poor judgment may increase. This indicates the disease has progressed to a moderate stage.
- Severe dementia鈥An individual with severe dementia may be unable to care for themselves or perform regular activities without assistance. Symptoms may not only impact their memory and thinking, but will also cause physical impairments in their bowel or bladder control or ability to stay awake.

Alzheimer's Disease Causes
Research is ongoing as scientists and doctors continue to study the cause of Alzheimer鈥檚 disease. Current data shows that a combination of genetic, environmental, and lifestyle factors may play a role in developing the disease:
- 础驳别鈥This does not directly cause Alzheimer鈥檚, but it is the greatest known risk factor for developing it. According to the , your risk of Alzheimer鈥檚 doubles every five years after age 65.
- Family history鈥You鈥檙e more likely to develop Alzheimer鈥檚 if a parent or sibling also has the disease. The more people in your family who have Alzheimer鈥檚, the higher your risk.
- History of brain injuries鈥There is a link between head injuries and later risk of dementia.
- Unhealthy lifestyles鈥An unhealthy diet, lack of exercise, and frequent tobacco and alcohol intake will increase your risk for Alzheimer鈥檚.
- Other health conditions鈥Heart disease, stroke, high blood pressure, high cholesterol, diabetes, and untreated sleep apnea have been linked to the development of Alzheimer鈥檚.
Alzheimer's Disease Diagnosis
The most definitive way to confirm Alzheimer鈥檚 is by testing someone鈥檚 brain tissue during an autopsy after death. However, patients who have one or more of the varying symptoms of the illness will be diagnosed with 鈥減robable Alzheimer鈥檚 disease鈥.
During the initial evaluation, we will ask questions about a patient鈥檚 cognitive decline, such as the types of cognitive problems they experience and the degree to which they impact their life. We ask that a family member, friend, or caregiver who is familiar with the patient鈥檚 symptoms accompany them. New patient visits and return visits typically last about one hour.
We may perform one or more of the following tests to make a diagnosis:
- Magnetic resonance imaging (MRI)鈥An MRI uses a computer, radio frequency, and a magnetic field to create pictures of the inside of your body. MRIs may reveal abnormalities in different areas of the brain, indicating cognitive impairment associated with Alzheimer鈥檚.
- Positron emission tomography (PET scan)鈥This scan uses small amounts of radioactive dye to allow neurologists to see inside your body. PET scans help to identify certain plaques in the brain that are indicators of Alzheimer鈥檚. Your provider may order a FDG-PET scan to show the metabolism of glucose in different parts of the brain. This helps identify a pattern of under-functioning associated with Alzheimer鈥檚 disease or frontotemporal dementia.
- Neuropsychological testing鈥We use a variety of neuropsychological tests to assess memory, reasoning, problem-solving, and other functioning. You may be asked to answer questions, write, draw, or respond to items on a computer.
Prognosis of Alzheimer's Disease
There is no cure for Alzheimer鈥檚 disease. The disease will become worse over time and is fatal. The estimates that most people diagnosed with Alzheimer鈥檚 will live for four to eight more years after their diagnosis, but that time may vary.
Alzheimer's Disease Treatment
There currently are no medications or surgical procedures that will reverse or slow down the brain changes that occur with Alzheimer鈥檚 disease. However, there are two categories of medications that can help to improve cognition temporarily.
Alzheimer's Disease Prevention
There is no proven way to prevent Alzheimer鈥檚 disease. However, research shows you can reduce your risk for developing the disease by living a healthy lifestyle and reducing your risk of cardiovascular disease and stroke:
- Exercise for at least 30 minutes of each day.
- Sleep for 7-9 hours of each night.
- Eat a well-balanced diet, such as the .
